"You can do what you want in this group, it's great!" Spice Girl Melanie B. told MTV News. "You can be as mad as you want, as normal as you want or as loud or as proud as you want!"

"And be whoever you wanna be!" bandmate Emma added.

"Just be happy, have a laugh so if you want you can run up and down with no clothes on, but if you do feel the need to all of a sudden do that... feel free," Victoria chimed in.
